Abstract
A microphone port design for a handheld device is disclosed. The microphone port design includes an elongated channel disposed in a first surface of the handheld device. A microphone port is located within the channel to reduce unwanted noise caused by air pressure build up around the microphone port opening due to coverage of the opening by a user's finger.
